Aphid Cluster Recognition and Detection in the Wild Using Deep Learning Models

no code implementations10 Aug 2023 Tianxiao Zhang, Kaidong Li, Xiangyu Chen, Cuncong Zhong, Bo Luo, Ivan Grijalva, Brian McCornack, Daniel Flippo, Ajay Sharda, Guanghui Wang

To facilitate the use of machine learning models, we further process the images by cropping them into patches, resulting in a labeled dataset comprising 151, 380 image patches.

On the Real-Time Semantic Segmentation of Aphid Clusters in the Wild

no code implementations17 Jul 2023 Raiyan Rahman, Christopher Indris, Tianxiao Zhang, Kaidong Li, Brian McCornack, Daniel Flippo, Ajay Sharda, Guanghui Wang

We have collected and labeled a large aphid image dataset in the field, and propose the use of real-time semantic segmentation models to segment clusters of aphids.

Gender, Smoking History and Age Prediction from Laryngeal Images

no code implementations26 May 2023 Tianxiao Zhang, Andrés M. Bur, Shannon Kraft, Hannah Kavookjian, Bryan Renslo, Xiangyu Chen, Bo Luo, Guanghui Wang

In this study, we made the first endeavor to employ deep learning models to predict patient demographic information to improve detector model performance.

Dynamic Label Assignment for Object Detection by Combining Predicted IoUs and Anchor IoUs

1 code implementation23 Jan 2022 Tianxiao Zhang, Bo Luo, Ajay Sharda, Guanghui Wang

For anchor-based detection models, the IoU (Intersection over Union) threshold between the anchors and their corresponding ground truth bounding boxes is the key element since the positive samples and negative samples are divided by the IoU threshold.

An Unsupervised Domain Adaptation Model based on Dual-module Adversarial Training

no code implementations31 Dec 2021 Yiju Yang, Tianxiao Zhang, Guanyu Li, Taejoon Kim, Guanghui Wang

In this paper, we propose a dual-module network architecture that employs a domain discriminative feature module to encourage the domain invariant feature module to learn more domain invariant features.

Miti-DETR: Object Detection based on Transformers with Mitigatory Self-Attention Convergence

1 code implementation26 Dec 2021 Wenchi Ma, Tianxiao Zhang, Guanghui Wang

Object Detection with Transformers (DETR) and related works reach or even surpass the highly-optimized Faster-RCNN baseline with self-attention network architectures.

Six-channel Image Representation for Cross-domain Object Detection

no code implementations3 Jan 2021 Tianxiao Zhang, Wenchi Ma, Guanghui Wang

If we train the detector using the data from one domain, it cannot perform well on the data from another domain due to domain shift, which is one of the big challenges of most object detection models.

Efficient Golf Ball Detection and Tracking Based on Convolutional Neural Networks and Kalman Filter

1 code implementation17 Dec 2020 Tianxiao Zhang, Xiaohan Zhang, Yiju Yang, Zongbo Wang, Guanghui Wang

The detection is performed on small image patches instead of the entire image to increase the performance of small ball detection.
